Science New Insight: Quantifying the Relationship Between Stress and Skin

SK-II conducted its own investigation into the relationship between stress and skin age. The results revealed that most of the factors causing skin aging are not genetic elements or changes due to age, but are caused by stress from lifestyle habits and the like. It was also found that life stress affects the expression of 701 genes. Furthermore, SK-II conducted further research on the relationship between stress and skin aging and obtained data. As a result, it was found that when stress is high, skin age increases by +1.8 years for those in their 20s to early 30s, and by +5.5 years for those in their late 30s to 40s.

Stress accumulation leads to actual age < skin age.

Concentrated Pitera™*⁶ and Micro Oil Beads Blended

'Facial Treatment Serum' is a rich skincare serum that contains SK-II's unique concentrated Pitera*⁶ and Micro Oil Beads*³, which were developed using new microfluidic technology to achieve a particle size of approximately 0.7mm. It has a thick, jelly-like texture that spreads smoothly on the skin, instantly delivering radiance with a unique feel. It also features a refined woody floral scent inspired by the rare Japanese Mizunara tree.

- Concentrated Pitera: Contains over 50 types of vitamins, amino acids, minerals, organic acids, and other components, and is a natural-derived ingredient that maintains the skin's natural health.

- Micro Oil Beads: Micro Oil Beads*³ are beauty ingredients themselves. Since the beads are not encased in a hard shell, the beauty ingredients blend smoothly into the skin, providing a non-sticky, non-greasy feel. Additionally, approximately 16,000 Micro Oil Beads*³ are contained in 50ml of the skincare serum.

- Mizunara Scent: A refined woody floral scent inspired by the Japanese Mizunara tree, which is also used for high-quality whiskey barrels. This is the first scent for SK-II products.

An Icon Symbolizing SK-II's Craftsmanship

'Facial Treatment Serum' reflects SK-II's dedication to craftsmanship. The distinctive lock sound when the bottle is closed and the package design featuring a padlock motif express the concept of 'locking in beauty'. The texture has also been carefully considered. The moment the jelly-like texture wraps around the skin, the beauty ingredients concentrated in the Micro Oil Beads*³ burst and penetrate*⁷, leading to skin that is radiant, firm, and moist with a soft, supple feel.
